Search Form Can't Be Selected In Safari (4 posts)

I installed WP 2.0 for a client and have it running fine. However, I've found that the search form cannot be selected and filled when using Safari (2.0.3). No problems in Firefox, just Safari. I suspect it might be the theme I modified not being 100% ready for 2.0. I'm reasonably new to WordPress, so I might be off base entirely. Can you please help?
